BlueRock is a rugged, waterproof sensor designed to wirelessly monitor the relative humidity and temperature of concrete from fresh to hardened stages.

BlueRock can be placed in the concrete at the pouring time to monitor the temperature and humidity of concrete in-situ. The continuous measurements are recorded on the BlueRock memory and can be downloaded at any time during the concrete setting and hardening using BlueRock mobile app on smartphone/tablet.

The continuous monitoring of concrete relative humidity and temperature can be used as a QC/QA method. By knowing the level of humidity in the concrete, flooring companies can decide on the timing of installation of floor covering (such as resilient flooring, epoxy coating, or wood) based on the type of concrete materials. Unlike the current destructive and time-consuming methods that measure only one data point at the testing time and require drilling a hole in concrete, BlueRock offers an embedded wireless solution for continuous measurement and accurate monitoring of internal humidity variations in concrete over time.

1 Accuracies are tested at Outgoing Quality Control at 25°C and 3.0V. Values exclude hysteresis and long term drift and are applicable to non-condensing environments only.
2 The wireless communication range is reduced as the sensor is embedded deeper in the concrete. The maximum recommended concrete depth for embedding the sensor in the field is 5 cm. At this depth, the user can communicate with the sensor within a couple of meters.
3 Normal operating range: 0-80%RH, beyond this limit sensor may read a reversible offset with slow kinetics (+3%RH after 60h at humidity >80%RH).
